I have a 94 EG with a 95 GSR engine swapped into it. I can get 2 good pulls past 5500 RPM, but then it goes into a limp mode and redlines at 5500 RMP. It has code 41 (o2 heater) not worried about that I am wiring in a 4 wire O2 sensor, but it also throws Code 22 (Vtec Pressure Switch) the wiring to the ECU is good and has good ground. is there a way to test the sensor with a MultiMeter? What kind of switch is it, an open and closed, or is it a actual pressure transducer where it reads actual pressure?
